WELL SCREEN CASING.

Application filed August 18, 1926.

This invention relates to casing or tubing from which well screen sections may be made for use in Water or like wells.

The chief object of the invention is to provide simple, inexpensive casing for the above purpose and capable of easy and economical manufacture.

Particularly the invention has for its object the construction of a casing from strip metal wound helically with the edges of the convolutions lap-jointed and riveted along said edges by hollow rivets providing the screen openings.

The foregoing and other objects are obtained by the construction illustrated in the accompanying drawings and described below in connection with its method of manufact-ure. It is to be understood that the invention is not limited to the specific form thereof shown and described.

Of the accompanying drawings:

Figure 1 is an elevation of a portion of casing embodying the invention;

Figure 2 is a detail elevation of a joint thereof at a rivet; and

Figure 3 is a section on line 33 of Figure 2.

Serial No. 129,883.

Referring to the drawings, 10 represents a strip of suitable metal wound helically into tubular formation with the edges of the convolutions overlapped as at 11, 11.

The convolutions of the strip are secured together by rivets 12, 12 of hollow tubular formation adapted to provide screen apertures 13, 13. 35

The manufacture of the above casing is exceedingly simple, many of the operations incident to the forming of ordinary casing and the punching of the screen apertures being avoided, the riveting operation and the formation of the screen apertures being accomplished as a single step.

Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claim.

What is claimed is:

A casing for use as a well screen, comprising helically wound strip metal, the edges of the convolutions of which are overlapped, said convolutions being secured together by tubular or hollow rivets extending through the overlapped edges, and providing screen apertures in said casing.
